Analysts at Piper Jaffray cut their price target to $52 from $56 as Ross management failed to elaborate on how they will address issues facing ladies' apparel.

"Ladies' apparel, which accounts for 29 percent of the company's sales ... was indicated to be an underperforming category," Piper said in a Thursday note to clients. "On the call held with investors to discuss results, we note that the precise issue, nor the timeline for fixing the problem, was shared on the call."
